> not untracking tuples that have refcount == 1. Actually, this may not be a good idea as well: running test_list shows that there are 14786 tuples with refcount == 1 that would have been untracked. This is a non-trivial workload to the gc passes that we will lose if we do this. Performance-wise, I think the best alternative is to force the tracking before visiting in tp_traverse.

Actually, this may not be a good idea as well: running test_list shows that there are 14786 tuples with refcount == 1 that would have been untracked. This is a non-trivial workload to the gc passes that we will lose if we do this.
